PV76-31A Proportional Flow Control Cartridge,
DESCRIPTION
A solenoid-operated, electrically-variable, three-port, pressure-compensated, spool-
type, normally open when de-energized, proportional fl ow control valve. It can be used
as a priority-type fl ow regulator with pressure-compensated, regulated and bypass
fl ow. It can also be used as a restrictive-type, two-way, pressure-compensated fl ow
regulator when the bypass line (port
➁) is blocked.
OPERATION
The PV76-31A will regulate fl ow out of port ➂ regardless of system working pressure.
With an increasing current applied to the solenoid, output fl ow will decrease.
Note: When used as a bypass fl ow control in applications where the priority fl ow port
will be blocked by external valving, bypass pressure drop will increase unless a small
amount of leakage is provided for the priority port. Consult factory.
Operation of Manual Override: To Engage: Turn clockwise approximately 1 turn to
reach start point. Continue another approximately 5 turns to full shift. To Disengage:
Turn counterclockwise approximately 6 turns to positive stop.
FEATURES
• Excellent linearity and hysteresis characteristics.
• Hardened spool and cage for long life.
• Optional coil voltages and terminations.
• Effi cient wet armature construction.
